Baltic Breakfast: The Baltic Sea food web in a changing environment

Webinar

Date: Wednesday 26 January 2022

Time: 09.30 – 10.15

Location: Digital event

Environmental changes have consequences for the Baltic Sea's food webs - and ecosystems. Upcoming Baltic Breakfast webinar will present two studies on environmental change and the food web.

 

 

Researcher Maciej Tomczak, Stockholm University Baltic Sea Centre, will share the results from an international project looking at changes in several factors over an 80-year period. Several large-scale ecosystem changes – regime shifts – have been identified. The interaction between benthic and pelagic species has weakened in the central Baltic Sea. Oxygen content controls the ecosystem more than before, while salinity becomes less controlling. Recently, fishing has had a greater impact on the food web.

The research of Eva Ehrnsten, Stockholm University Baltic Sea Centre, focuses on how changes in phosphorus and nitrogen inputs have affected different types of benthic animals since the 1970s. Despite widespread bottom oxygen depletion, the total amount of animals has increased. The composition is also affected. Reduced inputs of nitrogen and phosphorus and climate change may alter the picture in the future. 

Understanding how the system has changed over time is important when management targets are set. Welcome to a Baltic Breakfast to learn more about the food web changes and discuss management targets!
